HVAC Technician

We are seeking a skilled and experienced HVAC Technician with strong hands-on experience in the operation, maintenance, troubleshooting, and repair of HVAC systems in commercial, residential, and high-rise buildings.

The ideal candidate should have practical knowledge of AHU, FAHU, FCU, Package Units, VRF/VRV, chilled-water systems, BMS, VFD, refrigeration systems, and district cooling.

Key Responsibilities

HVAC Systems

• Operate, inspect, maintain, and troubleshoot AHU, FAHU, FCU, Package Units, and VRF/VRV systems.
• Perform preventive and corrective maintenance to ensure reliable and efficient operation.
• Monitor equipment performance and identify abnormalities or potential failures.

AHU & FAHU

• Monitor supply/return temperature, CFM, static pressure, filter DP, CHW flow, valve position, fan/motor, VFD, and BMS parameters.
• Troubleshoot cooling and airflow issues by systematically checking filters, CFM, coils, CHW, valves, actuators, sensors, and BMS.

VRF/VRV & Package Units

• Troubleshoot VRF/VRV systems, including outdoor/indoor units, inverter compressors, refrigerant piping, EEVs, PCBs, sensors, communication wiring, and controllers.
• Maintain and troubleshoot package units, including compressors, condenser/evaporator coils, fans, and expansion devices.

Refrigeration & Compressors

• Diagnose refrigeration and compressor faults using pressure, temperature, voltage, current, winding, insulation, oil, refrigerant, and mechanical checks.
• Identify the root cause of compressor failure before recommending replacement.
• Carry out compressor replacement, refrigerant recovery, pressure testing, vacuuming, charging, testing, and commissioning when required.

Chilled-Water & District Cooling

• Monitor CHW supply/return temperature, flow, ΔT, differential pressure, valves, and PICV.
• Support chilled-water balancing to ensure proper flow distribution to AHUs and FCUs.
• Maintain and troubleshoot district cooling components, including ETS, heat exchangers, CHW pumps, control valves, BTU meters, and flow meters.

BMS, VFD & Controls

• Monitor HVAC equipment through BMS and respond to alarms and abnormal operating conditions.
• Understand basic BMS functions including monitoring, control, alarm, trend, and scheduling.
• Operate and troubleshoot VFDs used for AHU fans, exhaust fans, and chilled-water pumps.
• Understand basic control signals including 0–10 V, ON/OFF, floating control, and feedback.

Electrical & Motor Troubleshooting

• Perform basic electrical checks on HVAC equipment, including voltage, current, phase sequence, overload, contactor, and motor condition.
• Understand basic three-phase motor starter arrangements and HVAC control circuits.

Indoor Air Quality

• Monitor temperature, relative humidity, CO₂, PM2.5, PM10, VOC, and fresh-air quantity.
• Ensure filters, ventilation, and fresh-air systems operate effectively.

Preventive Maintenance & Safety

• Carry out scheduled preventive maintenance and attend equipment breakdowns promptly.
• Maintain maintenance records and report recurring or critical equipment issues.
• Follow all company and site HSE requirements and safe working procedures.
